PURPOSE: An apparatus for collecting data using a DSP(Digital Signal Processor) is provided not only to suitably process digital signals suitably, but also to remarkably increase data collection capability by installing a DSP in a data collector so that the DSP can be operated as a CPU. CONSTITUTION: A DSP circuit, internally containing a global bus and a local bus for parallel operation, is composed of 6 communication ports, 2 timers, and other control signal lines. A local memory makes 64K*32bit using two KM6161002B chips. A global memory makes 256K*32bit using two KM616v4002 chips, and keeps measured data, the data processed at the DSP and the data transferred from a host PC. An EPROM using 27C256(256K) has a booting program. A PCI control circuit using a V360EPC chip is composed of a PCI interface and a local interface. A PLD decodes addresses and controls a signal formed at each chipset.
